Could you build this?

Partial Writing the ESP8266 C++/Arduino code to fetch APIs and render graphics onto an e-paper screen is straightforward, but physical hardware constraints, deep sleep power profiling, and hardware-specific debugging require hands-on electronics expertise. Vibe coding cannot solder, debug physical SPI pin connections, or physically tune low-power hardware circuits.

What it would actually take: Stack uses C++/Arduino or ESP-IDF with libraries like GxEPD2, consuming REST/JSON APIs over Wi-Fi, rendering 1-bit framebuffers, and entering deep sleep. The difficult parts include power-budget optimization (sub-mA sleep current, RTC waking, Wi-Fi fast-connect) and e-paper display waveform management to avoid ghosting without draining battery life. Requires an embedded developer with basic EE hardware lab access and multimeter/oscilloscope for sleep profiling.
